The present invention relates to a way of performing radiant heat-based convection heating that is based on hanging in a space and a case produced for an effective use of a planar heating element (front face application, including fabric). According to the present invention, the planar heating element is installed in the middle inside the space and heating is induced by means of radiant heat circulation and spatial convection, which differs from existing building methods that are vulnerable to a fire attributable to a thermal deformation of a heating element or moisture. Unblocked release of a large quantity of radiant heat has been ensured by an edge being fixed with the produced case such that no attachment is present on the surface of the heating element. The radiant heat-based convection method that is based on the hanging in the space and uses the high planar heating element in particular constitutes a clean and eco-friendly heating method for cultivation without environmental pollution when used for heating for industrial purposes and heating in agricultural plastic greenhouses vulnerable to heating in winter. The method based on the hanging in the space, which is unprecedented, allows primary heating that allows an indoor temperature of at least 13 degrees Celsius to 18 degrees Celsius, which is required for crop cultivation, to be maintained. In addition, installation for use at a low temperature, use at a high temperature, and the like can be performed with ease, and thus production can be performed for convenient use at farming households or non-farming households and without a significant burden regarding heating costs. As a result, the installation can be conveniently performed by anyone even without a specific orientation.COPYRIGHT KIPO 2017본 발명은 면상발열체(전면도포, 선상포함)를 효과적으로 사용하도록 케이스를 제작하여 공간에 걸이식 복사열 대류난방을 하는 방식에 관한 것으로 기존에 사용하던 수분이나 발열체의 열 변형에 의해 발생하는 화재에 취약한 시공방식을 벗어나 면상발열체를 공간의 내부중간에 설치하여 복사열 순환을 이용 공간대류현상을 이용하여 난방을 유도하는 방식이다.발열체의 표면에 일체의 부착물이 없도록 테두리를
